Tube fever...845 SET w/ Avalon


I'm seriously considering a switchover from my beloved Rowland 302 to a relatively high powered parallel 845-based SET -- the Mastersound 845 Reference. Speakers are Avalon Eidolon Diamonds.

Can anyone offer commentary on the ability of a high current 40 WPC amp to drive Eidolon Diamonds in a fairly small listening room? I realize that the majority of Eidolon Diamond owners would recommend either CAT, Atma-Sphere, VTL, BAT, LAMM, ARC or Tenor. These high powered amps will certainly deliver better, more defined low frequencies -- but the 40WPC SET may have an advantage in the mids and highs.

Any thoughts or recommendations? TIA.

For 845 amp, I've tried many different. IMO, Mastersound Reference 845 is the best. I did compare this amp with Nagra, Cary, Dehavillen, Art Audio quartet.. etc.
Currently own a 845 integrated amp and previous owned a Avalon Radian HC. I don't think a SET at 40W will be a good combination with Avalon speakers. Most SET don't do well into low impedance speakers even with 4 Ohm tap. Dynamic will be severely limited and distortion will be pretty obvious. Any chance to get a dealer loan before purchasing?

Need something much more efficient like Coincident speakers or horn.
Please read my email. I agree that 845 based amp is something special. It captures the texture & immediacy (?neologism or mispel) of the recording that bettered all amps I have owned or borrowed.
I use Avalon Eclipse Classic and NAGRA VPA. It sound pretty nice. I think Avalon Diamond must be used easily.
